James C; Barnes, Chicago, Ill. Application August 19, 1949, Serial No. 111,259

the cup to be poured therefrom or drunk di rectly from the cup, the primary object of the invention beingto' provide a device of this kind which enables hot or'cold liquid, dispensed from such as a vacuum bottle into a cup, to be kept hot or'col'd thereinlonger than otherwise would 'be the case, and toprotect the contents of the cup from contamination by dust, dirt and the like between drinks therefrom.

' to provide a practical, efficient and low-cost cover which is readily attached to and removable from -a cup or the like, such as the cup associated with a vacuum bottle, having a drinking and pouring opening closable by a slide which is operable as desired by the user.

Other important objects and advantageous features of my invention will be apparent from the following description and the accompanying drawings, wherein, merely for purposes of illustration, a specific embodiment of the invention is set forth in detail.

In the drawings:

Figure 1 is a top plan view, showing the cover closure in closed position;

Figure 2 is a similar view, with the closure open;

Figure 3 is a rear elevation;

Figure 4 is a transverse vertical section taken on the line 4-4 of Figure 1;

Figure 5 is a transverse vertical section, taken at right angles to Figure 4, on the line 55 of Figure 2.

Referring in detail to the drawings, wherein like numerals designate like parts throughout the several views, the numeral 6 generally designates a cup, such as a cup associated with a vacuum bottle (not shown), having a circular rim 1 from which the side wall 8 curvedly converges toward the bottom 9. Mounted upon the rim 1 and gripping the outside of the side wall 8 is the detachable cover Ill.

The cover [0 comprises a disc ll having substantially the same, or a slightly larger, outside diameter as the cup rim 1 and having secured to the under side thereof a circular gasket l2 to conformably engage the upper edge of the rim 1 and provide an air-tight seal between the disc H and the rim 1.

One side of the disc II is cut through its pe- 2 ripheral edge I3 to provide a substantially square drinking and pouring opening [4. The diametrically-opposite side of the disc I I has an extension |5 depending from and preferably formed on the peripheral edge I 3 and curved transversely and downwardly and inwardly to conformably and frictionally engage the subjacent area of the outside of the cup side wall 8 for a substantial distance below the rim 1.

Secured by suitable means upon the upper side of the disc H is a diametrical plate [6 terminating at its opposite ends in depending extensions ll, shaped'and curved like the extension [5 of the disc I l and equidistantly spaced from opposite sides thereof, to frictionally engage the outside of the cup side wall 8 and thereby firmly mount the cover It in place on the cup 6, with the gasket l2 compressed upon the rim 1.

The edge [8 of the plate l6 facing the disc extension I5 is straight, Whereas, an intermediate portion IQ of the opposite edge of the plate i6 is curved, as shown in Figures 1 and 2. The said curved intermediate edge portion l9 corresponds in length with an upwardly-offset portion 20 of the plate I6, which, with the upper surface of the disc ll, forms a closed parallel-sided slideway 2| for the slide closure 22.

The slide closure 22 comprises a parallelsided, flat plate 23 confined in the slideway 2| and having an up-turned finger piece portion 24 on the end thereof facing the disc extension [5. The finger piece 24 is arranged to engage the edge [8 of the plate It so as to limit movement of the closure 22 to fully closed relation to the pouring and drinking opening [4.

The end of the closure plate 23 opposite the finger piece 24 has an edge 25 curved to conform to the curvature of the peripheral edge I3 of the disc II, the edge 25 extending beyond the sides of the closure plate 23 along laterals 2t, 26 which define shoulders 21, 2'! to engage the adjacent edge of the plate It in the fully opened position of the closure plate 23.

The cover I 0 may be made of any suitable material or combinations of suitable materials, with the gripping fingers l5 and l1, I! being sufiiciently flexible and resilient to be capable of being sprung over the cup rim 1 into frictional conformance with the outside of the cup side wall 8.

I claim:

1. A cover for a container having a rim at the upper end of a side wall, comprising a plate adapted to rest upon the rim, a depending extension on the edge of said plate, said plate being formed with a drinking and pouring opening diametrically opposite said extension, other extensions depending from said plate in circumferentially-spaced relation to the first-mentioned extension, said extensions being arranged to frictionally engage the outside of the container side wall and maintain said plate engaged with the cup rim, a member on the upper side of said plate having a channel portion spaced upwardly from said plate and with said plate defining a slideway extending crosswise of said plate, and a closure plate slidably confined in said slideway and engaging the upper surface of said plate, said closure plate being movable from a position in which said closure plate completely closes said drinking and pouring opening to a position in which v said closure plate completely exposes said drinking and pouring opening, said member comprising another plate" secured to the upper side of the first-mentioned plate and having said. other extensions on its opposite ends.

2. A cover for a container having a rim at the upper end of a side wall, comprising a plate adapted to rest upon the rim, a depending extension on the edge of said plate, said plate being formed with a drinking and pouring opening diametrically opposite said extension, other extensions depending from said plate incircumferentially-spaced relation to the first-mentioned extension,- said extensions being arranged to frictionally engage the outside of the container side wall and maintain said plate engaged with the cup rim, a member on the upper side 'of said plate having a channel portion spaced upwardly from said plate and with said plate defining a slideway extending crosswise of said plate, and a closure plate slidably confined in said slideway and engaging the upper surface of said plate, said closure plate being movable from a position in which said closure plate completely closes said drinking and pouring opening to a position in which said closure plate completely exposes said drinking and pouring opening, said member comprising another plate secured to the'upper side of the first-mentioned plate and having said other extensions on its opposite ends, said channel portion of said memher being formed intermediate the ends of said vother plate and having parallel sides, and said gaging the parallel sides closure plate having parallel edges slidably enof said channel portion.
